Grant us, we beseech thee, so to venerate the sacred mysteries of thy body and blood, that we may ever taste within us the fruit of thy Redemption.

Fructus Redemptionis—the fruit of redemption is grace which Christ merited for us on the Cross—hence the metaphor. We already received grace in Baptism and the other sacraments. But the Eucharist is the Sacrament par excellence of grace. It contains the Author of grace in Person—not so the other sacraments which contain but a participation of the power of Christ. The Eucharist is the very store-house of grace, the very Orchard of the fruit of Redemption, the very fountain-head of the divine life, the very wine-press of the blood.
